“I’m not going into that. I think they should release the report. That’s where the evidence is, the information is. Let’s see the report,” Pelosi told reporters when asked if Mueller appear before lawmakers. “If they don’t have anything to hide, they shouldn’t worry.”

Asked if Mueller should testify, Pelosi says, "I'm not going into that. I think they should release the report."

“If we cannot reach an accommodation then we will have no choice but to issue subpoenas for these materials,” Nadler said. “And if the department still refuses, then it should be up to a judge — not the president and not his political appointee — to decide whether the committee can review the complete record.”

Mueller finished his 22-month investigation in March. The probe examined possible collusion between the Trump campaign and Russia in 2016 and obstruction of justice.

Democrats have pounced on Barr and Rosenstein’s determination, saying it should not be up to two Trump appointees to make that call. Reports have also surfaced that members of Mueller’s team are unsatisfied with the four-page summary that Barr sent to Congress, saying the evidence they found regarding obstruction of justice was stronger than he suggested.

“In the public domain there are comments that people on the Mueller team think that there’s a mischaracterization by the attorney general, I don’t know. There’s an easy answer to this: Release the Mueller report as soon as possible,” Pelosi said Thursday.
